This chapter explains the effects of nutritional stress during development, with a focus on the hippocampus and spatial memory. Research work done on spatial memory in birds has provided a clear link between the ecological need to store food, a relatively enhanced spatial memory used to retrieve the cached food, and the relative volume of the hippocampus, the brain region processing spatial memory. With the importance of spatial memory for the survival of certain bird species, the author predicted that hippocampal development, and hence spatial memory, would remain intact even under nutritional stress. The data in the chapter refute that prediction and suggest that constraints during development preclude the insulation of certain brain regions from nutritional stress. Also, favoring animals with better spatial learning might provide an easier path for natural selection to select for better parents to produce high-quality offspring, rather than resolving the potential developmental constraint issue.
